I was not a fan of Michael Jackson. I didn't hugely go for his music. I found his persona and general behaviour in adult life to be repugnant. He was either a pedophile, or dangerously and recklessly naive in his attitude to children.
However, his impact on late 20th century culture was undeniable. I don't doubt the sincerity of the grief shown for him today, even if I am not a part of it myself.
